HINGE.

S PEGIFICATION forming part of Letters Patent No. 653,370, dated July10, 1 900. Application filed November 18, 1898. Serial No. 696,813 (Nomodel.)

To all whom it mag concern:

Be it known that we, LOUIs WELKER, Sr., andWILLIAM N. 'WELKER, residentsof Williamsport, in the county of Lycoming and State of Pennsylvania,have in vented certain new and useful Improvements in Hinges; and we dohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use the same.

Our invention relates to an improvement. in hinges, and moreparticularly to pivothinges for mirrors, transoms, and the like, oneobject of the invention beingto so construct a device of the abovecharacter that it willoperate to retain the mirror, transom, or the likein any inclined or upright position.

A further object is to so construct a device of the above character thatit will by friction of one leaf of thehinge against the other maintainthe leaves at any desired position relative to each other.

A further object is to provide a device of the above character whichwill be neat in appearance, extremely cheap and easy to manufacture, andmost effectual when in use.

With these objects in view the inventioncomprises two leaves or members4 4. Each member or leaf 4 is provided with holes 5 for theaccommodation of suitable screws 6, whereby to secure samein place. Eachleaf 4 is provided on one edge with a flange or wing 7 (preferablyformed by bending up one side of the leaf) at right angles to the leaf 4and projecting between the mirror and support any desired distance. Theflange or wing 7 on each of said leaves or members 4 points on one orboth wings or flanges is held tight against the other wing or flange,and hence it will be seen that owing to the spring metal the projectionsor bearing-points on the wings will be held firmly against the otherwing, and thereby maintain the mirror in any position to which it isadjusted.

We would have it understood that we do not wish to limit ourselves toonly one projection on each wing or flange, as we may employ several, orwe may employ one or more projections on one flange and none on theother flange. 7 j v Instead of constructing our improved hinge as abovedescribed we may construct same as shown in Fig. 4. In this form of ourinvention we provide on e leaf '4 with a slot 10, which communicateswiththe hole or opening for the reception of the bolt or rivet 9 andextends to the upper edge of the Wing or flange, whereby to permit theremoval of the mirror from the frame or support by simply turning themirror until the wing or flange 7 secured thereto is at right angles tothe other flange or wing, when the projections or bearing-points will beout of engagement with the other wing or flange and permit the easyremoval of the mirror.

Various other slight changes might be resorted to in the general formand arrangement of the several parts described without departing fromthe spirit and scope of ourinvention, and hence we would have itunderstood that we do not limit ourselves to the precise details setforth, but consider ourselves at liberty to make such slight changes andalterations as fairly fall within the spirit and scope of our invention.

Having fully described our invention, What we claim as new, and desireto secure by Letters Patent, is-

A hinge comprising two leaves each having it wing or flange at one edge,each of said specification in the presence of two subscribwings orflanges having a projection or bearing witnesses.
